As you've said, your wife is aware, but holds some negative but ill-informed attitudes. This is where communication may help. Both of you probably have some things to learn not only about yourselves and you're relationship, but also about the nature of cross dressing. It's not a disease, a character flaw or a disability. It is one of many common aspects of humanity that make each of us special. Hiding it, repressing and denying cross dressing won't help you feel better and it won't increase your wife's understanding. As was stated earlier, you can repeat this cycle time and again, but with each repeat there is another chance of irreparable harm to your marriage. I hope you can begin to take small, constructive steps to avoid that eventuality.
